Lock for buiiglar-proof pockets

WILLIAM J. SCOTT, OF ALBANY, NEWv YORK.

LOCK FOR BURGLAR-PROOF POCKETS, &c.

Specification of Letters Patent No. 30,160, dated September 25, 1860.

To all whom it may concern:

Be it known that I, VILLIAM J. SCOTT, of the city of Albany, State of New York, have invented a new and useful method of constructing a lock to secure chain or wire defended pockets for clothes or other receptacles for valuable portable articles and securing them so as to be proof against the attempts of burglars to pick them from their proper opening; and I declare the following speciiication, with the drawing accompanying it as part thereof, to be a complete description of my invention.

Similar letters in the different figures denote the same parts of the apparatus.

Figures 5 and 7 show my lock; Fig. 6 a key for the same; Figs. l and 2 a pocket with the plan and methods of afiixing the lock.

It is made of two similar parts D and E in which o, C, are bottom flanges with small holes in them for the stitches by which they are to be secured to the cloth.

CZ, d, are two face pieces projecting from the surface leaving between them the niche f. hen the lock is shut the face pieces fit to and against each other.

Through those of one of the parts D there are made beveled holesI a m; and from the other of E project steel spring headed bolts L, 7L, being pins with rounded heads a little too large to enter the narrow parts of the beveled holes m, a, without compression, in order to permit which, a slit, (as shown at K which exhibits a bolt on an enlarged scale,) is out down into the head, so as to allow the opposite parts of the bolt to be compressed upon each other, enter into the narrow parts of the holes d, cl, and spring out when they enter the outward beveled parts, by this operation holding the two parts of the lock together with a grip proportionate to the spring of the bolt head. The lock being thus closed it will require a strong pry to force the faces apart, to open the lock. This is done by the key, Fig. 6, which is a shank s having a flat bit e, which fits into the niche f and being twisted around pries apart the faces and opens the lock, as shown at I, Fig. 5. A sharp edged wedge,

like the blade of a knife, if strong enough could effect the same thing, but it would require a sight of the lock and a deliberate operation to do it. To prevent this, the lock is to be placed, as shown in Fig. 2, inside of and below the mouth g, of the pocket, keeping the lock out of sight, unless when the mout-h is opened by the wearer in order to insert the key.

Fig. 7 shows another arrangement of the lock to prevent its being opened by a sharp edge, or by anything but a proper key inw serted within it. It is made like the one in Fig. 5, with only this difference that over the top of one part of it, from the other part of it, projects a flange 70, having in it an opening corresponding with the niche f for the insertion of the key, and a-narrow slit through its edge for the passage of the shank of the key as the lock opens. The key to open this form of lock is like the one shown at Fig. 6, but it will be seen that it cannot be turned around to pry open the parts, until the bit .e has passed below the flange ,7a. The flange prevents the forcing of the lock by a knife or any flat bar shaped like the bit, as can be done with the lock shown at Fig. `5.

With either of these locks I use one or more spring head bolts, for although one or two can be made strong enough for security, yet more would embarrass the operation of a burglar', and require more deliberation in opening the lock even with the key in hand. T further propose to make the locks, for certain uses, to be drawn apart by a strong pull with the fingers, dispensing with a key.

My invention will be seen to apply to wallets, reticules, satchels, portfolios and such receptacles for valuable articles.

I claim* i l The method of constructing a lock of two plates of metal, held together, when locked, by spring head bolts attached to one of the plates; passing through suitable apertures made in the other plate, together with the key for separating the plates; substantially for the purpose and in the manner set forth in the within specification.

IV. J. SCOTT.
